A Method for Preparing Metal Inner Electrode Paste Having High Dispersibility for Multi Layer Ceramic Capacitor Having High Capacity

摘要

The present invention relates to a method of manufacturing a metal paste for an internal electrode having excellent surface roughness and dispersibility used in manufacturing a high capacity multilayer ceramic capacitor. Per 100 parts by weight of metal powder, 0-1.5 parts by weight of dispersant, 3-7 parts by weight of ethyl cellulose resin and 30-70 parts by weight of terpineol solvent, after pre-caneteri mixing with high viscosity; The ceramic additive, dispersant, and terpineol solvent are premixed and low viscosity is dispersed by adding an ethyl cellulose resin binder to the premix, wherein the ceramic filler, dispersant, ethylcellulose resin and terpineol solvent are ceramics. Dispersing low viscosity such that 0-1.5 parts by weight of dispersant, 1-5 parts by weight of ethyl cellulose resin, and 30-150 parts by weight of terpineol solvent per 100 parts by weight of the common material; Mixing and dispersing the metal dispersion and the ceramic formulation dispersion to 10-30 parts by weight of the ceramic formulation per 100 parts by weight of the metal powder; Viscosity control and vacuum defoaming; And it provides a method of manufacturing a metal paste for the internal electrode comprising the step of filtering the cartridge.;Metal pastes prepared by this method have improved dispersibility and thus exhibit improved surface roughness, dry film density and plastic shrinkage.;Metal powder, common material, high dispersion, metal paste, internal electrode
